Accessorize Your Winter, Like Jessica Alba

With the East Coast between Polar Vortexes, now is the time to plan your outdoor style before the next cold snap hits. Those of us with considerable subzero temperature experience know that there are three secrets to staying toasty when roaming through winter weather––all of which were conveniently embodied by trendsetter Jessica Alba, as the always-stylish actress took a stroll through NYC.

1) Layer!Really, there's no better way to trap your body heat where it belongs (i.e. close to your body) than by layering up your outfit. Start with a tank, thermal, sweater, then top it off with a stylish overcoat like Jessica's double-breasted black pea coat. And she obviously knows that the same rule applies to your legs: thick leggings (with tights underneath on super cold days) keep you nice and warm, and high boots add another layer of protection.

2) Scarf it upYour grandmother warned you about the dangers of exposing your neck for a reason, and old wives tales aside, she was indeed correct. So wear a scarf. Jessica opted for a gorgeous fur muffler that definitely does the trick. On extra chilly days, you can even wrap that baby around your face if needed.

3) Hats are your friendAnd the bigger the better. Winter is one season where it's OK to have fun with oversized hats in fun fabrics like fur. Whether you prefer a beanie, fedora, or otherwise, a hat is key to prevent body heat from escaping and protect your sensitive ears.

And as Jessica demonstrates, we can follow these three rules and still look stylish. Bring on the Polar Vortex.
